Modern aircraft are equipped with growing numbers of electrical components that require power even when the aircraft is parked and all switches are off. The problem, according to Concorde Battery (Booth 3019), is that these parasitic loads can drain the battery to the point where it may allow engine start but not contain enough reserve power for emergencies.
